Before we start

There are many resources that can help you with learning to code in R. By far the best resource is the vast community of R users and developers and with every issue you run into, you can almost guarantee that someone else had the same question previously. Forums like stackoverflow usually have really helpful answers to questions you may have.

One of my favorite formal training modules is the swirl package, which helps you learn how to code in R by… well, making you code in R. However, before that, you will have to install and organize your R software. The primer below will help you do just that.

Structure of coding lesson pages

All of the sessions are structured in the same way, presenting the following materials:

• A narrated slideshow that demos the content we’re working on
• The slideshow itself, which allows you to click links, copy code, etc.
• A set of training exercises, marked as either ‘Homework’ or ‘Classwork’
• Solutions to the training exercises, which will come online after class
